Announced in May 1984, the OASYS Lite from Fujitsu was the industry's first portable Japanese language word processor. The previous My OASYS2 weighed 11.9kg, but the OASYS Lite had an integrated keyboard and printer, and achieved greater compactness, lighter weight (3.5kg) and lower price. This machine had the following features:
(1) It achieved greater compactness and lighter weight by using state-of-the-art high-integration semiconductor technology, and, due to greater power conservation, was the first Japanese word processor to be driven by dry cells (4 "D" batteries).
(2) It employed the thumb shift keyboard and interactive kana-kanji conversion system, which had a proven track record in the OASYS Series.
(3) 8 char. x 1 line liquid crystal display
(4) Equipped with a comprehensive dictionary of approx. 40,000 words
(5) It could handle English, German, French and Spanish, as well as Japanese.
(6) A newly-developed, quiet 24 dot thermal transfer printer was integrated into the main unit.
(7) It was equipped with a document memory backup function. (This memory stored about two A4 pages when power was turned OFF.)
(8) Bubble memory (optional, capable of storing a max. of 40 A4 pages) was used as an external memory unit
In July 1987, the OASYS LiteS was announced as the most inexpensive Japanese word processor equipped with phrase conversion capability.
